Just depends what Strawberry flavors you use. If you want a strawberry flavor that only gets better as it steeps, I recommend inw shisha strawberry mixed with RF SC strawberry. Those two go great with custard as well.

That works. In my favorite strawberry cheesecake I use 2% fa strawberry and 1% tfa strawberry ripe along with .25% inw shisha strawberry. I can't say how long it'll hold up because 240ml only lasts me about 6 or 7 days!
